If you own a multimedia LCD or DLP projector, you will know that replacing the projector’s lamp is something that sooner or later you will need to do. The average projector lamp’s bulb lasts for around 2,000 hours, so most projector users will need to replace their lamp on average at least twice over the life of the projector. Since projector lamps can be expensive, it is important that you have the most accurate and up to date information about projector and TV lamps before you buy.
